Open ports on megabus to Boston

The following is nmap output over Megabus-provided wifi (en route to Boston) showing the proxied ports.

Starting Nmap 5.00 ( http://nmap.org ) at 2010-11-02 19:39 EDT
Interesting ports on dagny.detechnis.com (173.255.227.97):
Not shown: 987 filtered ports
PORT     STATE  SERVICE

80/tcp   closed http
110/tcp  closed pop3
143/tcp  closed imap
443/tcp  closed https
465/tcp  closed smtps

995/tcp  closed pop3s
1863/tcp closed msnp

Nmap done: 1 IP address (1 host up) scanned in 30.28 seconds

What’s sort of annoying is that:

  1. Port 22 (ssh) is blocked.
  2. ICMP Time Exceeded messages are blocked (not shown), making tracepath unusable.

I will be attending the Linux Plumbers Conference and the Beer Advocate Belgian BeerFest in the coming days. More on those as they happen.
